Y

A practical enibodiment of the invention is represented in the accompanying' drawings forming a part of this specitication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a reduced plan View of the cotton cleaner and separator; Fig. 2 isfa sectional side elevation of the 'same on the line 2-2 of Figrsal and 3; Fig. 3 is a transversesection of the same onthe line 3-3 of Figs. 2 and 4; Fig. 4 is a rear side elevation of thesame, with the driving shaft insection-on the line 4 4 oFigB Fig. 5 is an enlarged sectional side elevation of a portion of the separating saw drum, the section-being on the line 5.-5 of Fig. (3; Fig. is a cross section of the same on the line t3`t3 of Fig. 5; and Figa@ .is a cross section'of part ofthe grate and the means for actuatingthe same, the section being on the line 747 of Figi. 2.

The outer ends" of the shafts D2 and l)3 n re-pro\'itled'\\'ith pulleys E and E around which passes a belt F, and on the shaft Du Ais secured a pulley G connected by a belt -wu h other nia-chu'iery for impartinga rotary inet-ion to the beater D' anda travelingmotion to the belt l? to rotate the beater D in 'unison' with the beater ,DJly reference to the arrows in Fig. 2, itwillgbe noticed that the beaters l) and 1) are rotated simnl# in opposite directions. The beater arms Dhand D are spaced apart a distance than the diameter-olil a half open boll of cotton so that; the bells passim.l

between the beaters l) and D are, crushed andiopened by the heater arms D", Di' and the hulls of the bolts are partly separatedandloosened from the cotton tibers.

-I'n the rear ot the beaters l) and l)-1s ar- .rafngred a separatingsaw drum ll*k provided with a transversely-extending' shut-t l -jour- 'naled in a casingv and ,on the outer end of theshatt I is seeured'a pulley l around which passes the belt F, sol that `when the machine is running a rotary motion is transf' mitteilte the st nvfdrum H in the direction of thez'irrow o shown in Fig. Q.
